In this episode of DIY or Buy we will have a closer look at a small commercial 12V DC Water Pump. We will find out how it works and why it is called a centrifugal pump. Afterwards I will then 3D print a bigger water pump in order to find out whether it makes sense to DIY such a pump with a 3D printer or whether we should stick to the commercial solution instead. Let's get started!

Thanks to Trinamic Motion Control for sponsoring this video and sending an early version of their DOCK5 board, which features the ROCINANTE chip with integrated RISC-V processor.
